Sentence examples for use constellations from inspiring English sources
In fact, they use constellations with at most 4 bits/symbol.
where the signal-to-interference ratio (text {SIR}=frac {sigma ^{2}_{h_{ba}}}{sigma ^{2}_{h_{aa}}}) assuming both nodes use constellations with the same average energy, the desired signal-to-noise ratio (text {SNR}=frac {sigma ^{2}_{h_{ba}}log _{2}{(M }E_{b}}{N_{0}}), E b is the average bit energy which is defined below (2) and N0 is the noise power spectral density.

Using constellations of military and civilian satellites and ground-based computers and tracking stations, Pentagon commanders can often peer through the proverbial fog of war.
A well-known practical implementation of superposition coding is hierarchical modulation, also called layered modulation, which uses constellations with non-uniformly spaced signal points creating different levels of error protection.
Hierarchical Modulation (known also as embedded or multiresolution modulations) is one of the ways to implement the superimposition of multichannel signals, which uses constellations with nonuniformly spaced signal points.
Maximal achievable rate region for superposition coding and superposition modulation is obtained using constellation shaping.
To evaluate the NeLS's ISL performance, the structure for ISL connections was simplified by using constellation parameters of 121/11/0 instead of 120/10/1.
It can be observed that the TR system range of the used constellation orders is higher than that obtained for the two other systems.
A node, supporting the used constellation, performs soft demodulation and calculates symbol log-likelihood ratio (LLR) [17] and then converts to bit LLR.
